Question

three desks and a bookcase together weigh 157 lb. The bookcase 34 lb. How much does each desk way. Write and solve an equation.

Answer 1

Explanation:

Let "d" represent desks:

157 = 3d + 34

You would then subtract 34 from 157:

123 = 3d

You would then divide 123 by 3, since you are now finding the weight of 3 desks:

123

----- = d

3

Therefore, d = 41 lb.
